.SH NAME
check\-hostname \- check if sendmail can determine the system's
fully\-qualified host name
.SH SYNOPSIS
\fBcheck-hostname\fP\ [\ \fIoptions\fP\ ]
.SH DESCRIPTION
The check\-hostname script is a migration aid for \fBsendmail\fP(1M)\&. This
script tries to determine the local host's fully\-qualified host name (FQHN) in
a manner similar to \fBsendmail\fP(1M)\&. If check\-hostname is able to
determine the \fBFQHN\fP of the local host, it reports success\&. Otherwise,
check\-hostname reports how to reconfigure the system so that the \fBFQHN\fP
can be properly determined\&.
.SH OPTIONS
.OP h help flag -

.OP F functions flag -
Print out the list of all defined functionsi in this script and exit\&.
.OP T trace string fnlist
